model of Vitessʼs VTAdmin component. We first outline the core components of VTAdmin. We then cover how it interacts with the internal components of Vitess. Next, we specify the threat actors that could have we exemplify several threat scenarios based on the observations we made when outlining the core components and the specified threat actors. We used the following sources for the threat modelling: ● Vitessʼs disclosures to the Vitess security team are opportunities to evaluate the threat model of the affected components. Most compromises of VTAdmin have the goal of compromising the full Vitess deployment. As such

gain better understanding of the general deployment structure and the integration with the core components. • The initially enumerated application endpoints were tested for potential input manipulation Nothing prone to being leveraged could be identified. • The runtime behavior of the different components was probed from a perspective of the services. In focus were Denial-of-Service and similar resource-depletion easy for the auditors to review the software’s structure. Except for the SQL parser, none of the components had overly complex logic or included typically vulnerable constructs. The above factors
